How to adjust sound without converting/encoding?

[slipknot!]

I have an English sound from a movie. It's 01:42:56 minutes long. And I have it's translation in Russian. But the second one is 01:39:18 and doesn't have any others sounds except the speech.
How can I change the English speech with the Russian one without getting it converted?

Please write your answer using not too hard words, I'm so bad in Eng :rolleyes:

I think this is practically impossible without editing and re-encoding the audio.

If you have access to the original unmixed music and sound effect tracks, it is easy to mix them with any speech track using common audio editing tools. Removing the English speech from a mixed sound track can be a difficult problem unless you are dealing with 5.1 audio where most of the speech is put to the center channel. Then you can simply swap that channel with the Russian speech track and re-encode to a suitable format.

Yes, it is 6 channel sound.

If you have an .avi file, you can replace the audio track with VirtualDubMod (Streams > Stream List), then adjust the playback speed of the video so it matches the audio length (Video > Frame Rate...). Neither the audio nor the video will be re-encoded - you will only have to save the file (In Direct stream copy mode) with a new, unique file name.

Hi!

I believe the OP desires to replace the speech portion ONLY of the audiotrack, while retaining all other audio sounds/effects from the original audiostream...
